Google GSI: Generic System Images for Smartphones

After building my own ROM i got some problems with the devices drivers for the modem (the dual SIM was not recognized).

I discussed that with a few very skilled Android developers and the device drivers are the most important problem for building ROMs.

But there is something called GSI: Generic System Images.

(s. https://source.android.com/setup/build/gsi)

and:

The good point is that for my Samsung J530 there was a developer which built a project which allows to install GSIs:

With this plus Havoc 3.5

And here the steps to Android 10 (which where provided to me by Micro[ice]:

1. install TWRP 3.3.0
   
2. install create vendor 2.0
3. reboot recovery
4. install project spaget x
   (if u get symlink error 7 flash revert vendor 2.0 and repeat from step 1 without revert vendor 2.0)
5. install GSI (Havoc)-OS to system partition
   (dont reboot after u flash project spaget x)
6. if u need to flash gapps first u need to go
   Wipe -> Advanced Wipe -> Tick System -> Repair -> Resize
   (if u get error 1 resize again it will be successful) then u flash gapps
7. (optional) flash areskernel rc2
8. (optional) flash magisk
9. reboot
10. enjoy

And after that i have a running Android 10 on my Samsung J5... (without any Samsung Bloatware)
